Which term describes a system that uses knowledge-based rules to solve complex problems?

• A. GPS
• B. Expert System
• C. CAD
• D. Hardware

Answer: (B)

A system that uses knowledge-based rules to solve complex problems is an expert system. It relies on a knowledge base filled with domain-specific facts and rules, and an inference engine that applies those rules to current data to draw conclusions or make recommendations. This setup lets the system imitate the decision-making process of a human expert, handling intricate situations by chaining together rules like if-then statements and weighing their applicability. This approach is especially useful in areas where expert judgment is important, such as medical diagnosis, troubleshooting, or complex configuration tasks. The other options describe different technologies: GPS provides navigation data, CAD is for computer-aided design, and hardware refers to physical components, none of which operate as knowledge-based rule systems.
